高新区（滨江）科技创新开启“万物可炼”绿色革命

Core Insights - The article highlights the innovative technologies developed by companies in Hangzhou High-tech Zone (Binjiang) that transform waste into valuable resources, contributing to a "green refining revolution" driven by technological innovation [4][10]. Group 1: Waste-to-Energy Technologies - The "oil-water separator" patented by Weifulai Technology enables precise extraction of waste oil from kitchen waste, achieving an oil recovery rate of 3%-5% from 100 tons of kitchen waste, potentially yielding 3-5 tons of oil daily [6][10]. - China United Engineering's automated pyrolysis production line processes 20,000 tons of waste tires annually, producing approximately 48% pyrolysis oil, 40% carbon black, and 12% combustible gas, with the oil priced at around 4,000 yuan per ton [7][10]. - The low-temperature degreasing energy-saving and carbon-reducing device developed by Luhong Technology uses hydrodynamic cavitation to achieve effective oil removal, reducing waste liquid emissions by over 50% and saving 1.2 million yuan in energy costs annually for a single paint shop [9][10]. Group 2: Environmental Impact and Economic Benefits - The technologies implemented by these companies not only reduce waste but also create a circular economy, where by-products are reused in manufacturing processes, exemplified by the recycling of carbon black back into tire production [7][10]. - The integration of these technologies into various industries, including automotive manufacturing, demonstrates a significant reduction in carbon emissions, with one example showing a decrease of 1,540 tons of carbon emissions annually [9][10]. - The Hangzhou High-tech Zone aims to establish a comprehensive circular economy industry chain, continuously updating its "dual carbon industry map" to support the construction of a "waste-free city" [10].
